=== Eviction and Expiration
|
|
|
|
There are multiple different caches configured for {project_name}.
|
|
There is a realm cache that holds information about secured applications, general security data, and configuration options.
|
|
There is also a user cache that contains user metadata. Both caches default to a maximum of 10000 entries and use a least recently used eviction strategy.
|
|
Each of them is also tied to an object revisions cache that controls eviction in a clustered setup.
|
|
This cache is created implicitely and has twice the configured size.
|
|
There are also separate caches for user sessions, offline tokens, and login failures. These caches are unbounded in size as well.
|
|
|
|
The eviction policy and max entries for these caches can be configured in the _standalone.xml_, _standalone-ha.xml_, or
|
|
_domain.xml_ depending on your <<_operating-mode, operating mode>>.
